A real world example of a whitelist would be if two companies wanted to exchange email only with each other. These companies could implement a whitelist that contained IP address for just two email servers that want to send email to each other. That would mean that any email coming from an IP address not on whitelist would be returned to sender. For companies they can ensure that employees are only dealing with work related email and not chatting with their friends.

The benefits of whitelists are many but proper management of whitelists is equally important. Misuse of whitelists will only lead to more headaches for everyone involved with missing email, irate customers and IT departments doing overtime just being tip of iceberg.

Yet, I soon noticed that there was an added benefit ! I was able to eliminate majority of spam emails that was in my inbox. I just clicked blacklisting most of offending emails without downloading email. This has been quite a time saver!
